Cochrane journal published a review of Professor G. Bjelakovic about the impact of vitamin D on mortality of elderly patients. This review has allowed to establish that regular intake of vitamin D for 2 years reduces mortality by 6%.
In numerous medical studies and observations, it was noted the positive impact on health optimal levels of vitamin D in the human body. In particular, a marked reduction in cardiovascular and oncological diseases. This gave the background for the analysis and writing of this review.
The review analyzed the results of 50 clinical studies covering 94 148 elderly patients. All participants were from countries with high income, average age 74 years. Participants regularly for about two years, received supplements containing vitamin D active in various forms.
The analysis of the obtained data it was found that not all forms reduce mortality. On this endpoint does not affect the active form of vitamin D (calcitriol and alphacalcidol), vitamin D2 (ergocalciferol). We found a decrease in mortality of 6% only in patients taking the form of vitamin D3 (cholecalciferol). In addition, the best of mortality decline has been observed in women.
Also in the analysis included patients receiving combined form of vitamin D3 with calcium. In these patients, a fixed side effect is the formation of kidney stones (renal disease).
Data from this survey allow us to assert that supplementation with vitamin D3 is indicated for the preventive administration to elderly patients and reduce mortality. It is important not to forget that vitamin D3 is fat-soluble and can be deposited in the tissues of the body, and the means of achieving toxic effects in overdose.
